It matches your output:
 francesco@tya64:~$ update-alternatives --display mozilla-javaplugin.so
mozilla-javaplugin.so - auto mode
  link currently points to
/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so - priority
1061
Current 'best' version is
'/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so'.

For me (I use v 6):
 francesco@tya64:~$ dlocate
/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
icedtea-6-plugin:amd64:
/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
francesco@tya64:~$

Bob:
You hit the point.
Now, at least from academic centers,  I can see all the molecular
